1 Claim.

'This invention relates to elevator buckets, and has for the primary object the provision of a device of the above stated character which will completely empty itself when dumped by preventing the development of a partial vacuum therein and also will travel through the return leg of a conveyor housing without generating air currents therein which heretofore exist withthe use of the conventional type of buckets, and which air currents cause considerable trouble in replacing of inspection doors after their removal to permit inspection to be made to the interior of the conveyor housing.

With these and other objects in View this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of our invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a perspective view illustrating a bucket constructed in accordance with our invention.

Figure 2 is a front elevation illustrating the same.

Figure 3 is an end elevation illustrating the dev1ce.

Figure 4 is a plan view illustrating a blank from which the bucket is constructed.

Referring in detail to the drawing the numeral I indicates a bucket constructed from a single piece of material. The material is cut or stamped in the form of a blank 2, as shown in Figure 4. The blank is folded and bent on the dotted line disclosed in Figure 4 to form angularly related walls 3 and 4 and side members 5. The side members are arranged on an inclined plane between the portions 3 and 4 leaving openings or spaces 6 allowing escape of air from the bucket when in use to prevent partial vacuum from being developed in the bucket. The portion 4 is bent upon itself to form a retaining flange 'l and the portion 4 and ange 1 are provided with aligned openings-8 for the purpose of receiving bolts or like fasteners securing the bucket to a conveyor belt. The side members 5 are bent on the dotted lines shown in Figure 4 to lie between the flange 'I and the portion 4 and are provided with openings 9 to align with certain of the openings 8 so that the members 5 are secured to the portion 4 by the fasteners employed in securing the bucket t0 the conveyor belt. The free edge ofthe portion 3 is bent or rolled to form a beading l adapted to act as a reinforcement and also providing to the portion 3 a finished free edge.

A bucket constructed in accordance with the foregoing and operating on an endless conveyor Within a conveyor housing will more readily empty itself when properly positioned due to the openings 6 permitting air to escape from the bucket and consequently obviating the possibility of a partial vacuum to be established therein, which would have a tendency to hold or prevent the entire load of the bucket from emptying therefrom. A bucket of this character when traveling on the return leg of the conveyor housing will aid in reducing air currents in the housing to a minimum.

While we have shown and described the preferred embodiment of our invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of our invention, as claimed.

Having described the invention, we claim:

A bucket comprising vertically and horizontally arranged and integrally connected walls, side members integral with the horizontal wall and bent to engage one face of the vertical wall, said side members spaced from the .horizontal and vertical walls where said walls join each other to form openings, a ange formed on the vertical wall and overlying the ends of the side members, said vertical wall, the iiange and the ends of the side members having aligned openings to receive fasteners for securing the vertical wall to a conveyor belt and simultaneously securing the ends of the side members to. the vertical wall, said horizontal wall having its free edge rolled to form a beading;
